Very Computer

Before:
Node 1 and Node 3 shared 2 loops (loop A=disc 1-8 and loop B=disc 9-16) on
discbay 1.
Node 5 had exclusiv access to discbay 2 (loop A=disc 1-8 and loop B=disc
9-16)
Bay1: 2x4GB and 12x9GB
Bay2: 2x4GB and 13x9GB

After:
Node 1, 3 and 5 have all mutual access to both Discbays (loop A=disc 1-16 of
bay1 and loop B=disc 1-16 of bay2)
Bay1: 2x4GB and 13x9GB
Bay2: 2x4GB and 12x9GB

One 9GB-disc was taken from bay2 and inserted in bay1 at the beginning of
the reconfiguration.

The problem is that before the start of all this I had configured three
raid-5 arrays on node1 which got the state offline after the action. Any
attempt to delete one of the raids resulted in the messaged 'Object
xxxxxxxxx(Raid-Identifier) is broken'. Anyhow the discs which make up the
array are all there and marked as good.
I'm also not able to define a new raid although there are enough disks of
state free in both loops.
When i enter the dialog to add the new raid and i activate the select list
for the members then both lists (loop A, loop B) are empty.
Fortunatly I have no important data on the raid but I need to revitalise the
discs.

Anybody any advice for me ?????

: : We did some reconfiguration on our SP-Cluster concerning SSA-Loops.

: : Before:

:
: There are two things happening here, so far as I can tell.
:
: One is that the reconfiguration of the loops resulted in
: the loss of the original arrays.  I suspect that if you
: do:
:
: # ssaraid -Il ssa<n>
:
: where n is the adapter number on each node, you will see the array
: identifier instead of an hdisk name in the first line of the
: array stanza.  When this has happened, I've always had good
: luck with the 'Delete Old Array' panel in the 'ssaraid'
: fastpath panel.
:
: The other problem is that the drives that you're trying to
: use to build the array have a 'use' attribute of either
: 'system' or 'member'.  In order to use a pdisk to build
: an array, you must first change its 'use' to  'free'.
:
: You can confirm this with:
:
: # ssaraid -Il ssa<n> -n pdisk<n>
:
: And you can correct this in one of two ways.
:
: # ssaraid -H -l ssa<n> -n pdisk<n> -a use=free -u
:
: for each of the pdisks you want to use as member
: disks in the new arrays.
:
: Or -- and it might be a lot easier and faster to use this method given
: the number of disks your operating on  -- use the 'Change Use of Multiple
Disks'
: panel in the 'ssaraid' fastpath panel.
:
: So,
:
: 1) smitty ssaraid -> Delete Old Array

I tried  this before but the list off old arrays is empty

: 2) smitty ssaraid -> Change Use of Multiple Pdisks

The member discs of my 'offline' raids are not shown in the list which is
generated as select list for this option. When I selected one single disc in
the 'Change/Show Use of Pdisk' than he wrote 'Member of an SSA RAID' in the
current use field and when trying to select a different status he does not
create a select list.
I also tried your suggestion:
 ssaraid -H -l ssa0 -n pdisk5 -a use=free -u
This produced:
 ssachg: Resource 000629CBFE6300D is offline or unknown
 ssaraid: Change method failed for 000629CBFE6300D
The output of ssaraid -I -l ssa0 -n pdisk5 is:
 name           pdisk5
 id                000629CBFE6300D
 class           disk
 use              member
 blocksize    512
 size             9.1GB
 state            good
 fastwrite     off
I also did a certify with diag->SSA service aids for pdisk5 and the
certification finished without reporting any problems

: 3) smitty ssaraid -> Create New Array
